high cpu usage after update to MacVim r179 (Vim 9.1.0)

Steps to reproduce

1. Update to MacVim r179 (Vim 9.1.0)
2. Use it

Expected behaviour

Fairly low CPU usage.

Version of Vim and architecture

MacVim r179 (Vim 9.1.0), arm64

Environment

Operating system: macOS 13.5.2 (22G91)
Arch: arm64

How MacVim was installed

Logs and stack traces

I'll attach a sample taking in Activity Monitor.

I only have 6 windows open. Usually I have way more, and CPU usage is negligible. Now it hovers at around 12%.

I use very few plugins.

Commencez par reproduire l’utilisation élevée du CPU avec MacVim r179 (Vim 9.1.0) sur arm64 macOS 13.5.2, puis comparez le comportement de l’interface graphique signalé avec une configuration propre. Le problème est résolu lorsque la source de l’utilisation soutenue du CPU est identifiée et qu’une utilisation faible normale est rétablie.
